For the OCR and Voting disk creation, your text says to use "/dev/raw/rawX" but your screenshots say "dev/sdX". I presume the latter is the right way to do it, now that raw devices are more or less deprected in OEL/RHEL/CentOS 5.

No problem. If I may, I'd suggest mentioning something in the beginning of the article about mounting the installation media from an ISO or NFS mount (or adding 2GB more disk), so dolts like myself aren't left with an unpleasant realization at the end of the software install.
